A sworn police officer is among a group of 10 people arrested today in an Auckland drug bust.

Peter Pakau and his nine co-accused, including his wife, appeared at the Waitakere District Court this afternoon where he was refused bail.

The father-of-five is accused of supplying, conspiring to supply, possession of and manufacturing a class A controlled drug.

Other charges include conspiracy to commit aggravated robbery, conspiring to defeat the course of justice and accessing a computer for dishonest purposes.

Pakau, who has been a police officer for six years, was denied interim name suppression so as not to cast suspicion on other policemen.

He will reappear in court for a plea inquiry hearing next month.

Earlier today, Detective Inspector Bruce Scott said the arrests came after a "lengthy investigation into serious criminal activity involving the manufacture, supply and distribution of hard drugs an other offending".
